The electrons in an atom that are in orbits away from the nucleus are called valence electrons. Nitrogen: 5, Silicon: 4, Oxygen: 6, Magnesium: 2.
<h3>What exactly is a positive electron and why is it significant?</h3>
Valence electrons are the electrons that reside in an atom's outermost shell. The role of valence electrons in controlling an atom's reaction makes them crucial. By writing an octet, you'll be enabled see how many protons fill the highest amount of energy.
<h3>What is valence defined simply?</h3>
In chemistry, valence, sometimes called valency, is a characteristic of an element who establishes how many other atoms of the element each atom can interact with. The phrase, which was first used in 1868, is used to represent both the broad capability of pairing of an element and its numerical value.

Hey there!:
Temperature in kelvin : 45 + 273 => 318 K
Number of moles H2:
p * V = n * R * T
4.46 * 0.579 = n * 0.082 * 318
2.58234 = n * 26.076
n = 2.58234 / 26.076
n = 0.09903 moles of H2O
Given the reaction:
XeF6(s) + 3 H2(g) → Xe(g) + 6 HF(g)
Molar mass XeF6 = 245.3 g/mol
0.09903 mol H2O * ( 1 mol XeF6 / 3 mol H2 ) * 245.3
= 8.09 g of XeF6
Hope that helps
Answer:
I think It's C
Explanation:
due to higher waves can get easy transfers and receive those signals for most things, such as radios, TVs, phone signals etc etc
Answer: Option (a) is the strong acid.
Explanation:
Hydrochloric acid is a strong acid and when it is added to water then the following reaction takes place.
![HCl + H_{2}O \rightarrow H_{3}O^{+} + Cl^{-}](https://tex.z-dn.net/?f=HCl%20%2B%20H_%7B2%7DO%20%5Crightarrow%20H_%7B3%7DO%5E%7B%2B%7D%20%2B%20Cl%5E%7B-%7D)
where,
is a conjugate acid and
is a conjugate base.
Therefore, when we add HCl into water then it dissociates completely into hydronium ion and chlorine ion.
Thus, we can conclude that a strong acid is disassociated completely, producing more conjugate base.
